Decay Data Evaluation Project

High-quality evaluated nuclear and atomic data, such as half-life, decay mode and branchings,
radiation energies and emissions probabilities, are needed in applied research and for detector calibrations.

In 1995 an international collaboration was formed, the Decay Data Evaluation Project, which includes members of the
BNM-CEA/LNHB (France), PTB (Germany), INEEL (USA), KRI (Russia), LBNL (USA), NPL (United Kingdom), CIEMAT (Spain),
with the objective of providing carefully produced recommended data.

Updates of recommended data pages are realized by the Laboratoire National Henri Becquerel.
